To aZZ whom, it may concern.-

Be it known that I, EDGAR S. BASSETT, of Cadillac, in the county of\Vexford and State of Michigan, have invented new and usefulImprovements in Heating Apparatus, of which the following is aspecification.

In the accompanying drawings, Fi gu re 1 is a perspective view, partlyin vertical section, of my improvements applied to astove. Fig. 2is aperspective view of the base portion of the apparatus, the outer portionthereof being shown in dotted lines only, so as to more clearly indicatethe interior construction. Fig. 3 is a plan view of a modified form ofthe base portion; and Fig. 4 is a central vertical section of the baseshown in Fig.3, the position of a stove thereon being indicated indotted lines.

The principal feature of the invention consists in a hollow base whichis placed upon the floor and upon which the stove or furnace is set.This base has a central chamber, to which ducts or passages lead fromthe exterior of the base. From this central chamber anupwardly-extending pipe or flue leads,which carries off the air fromsaid central chamber and id duces a draft through the base.

Referring first to .Figs. 1 and 2, A is the 1101 low base, having aninterior central chamber, D. Extending from the outer walls of the baseto the central chamber are a series of open passages or ducts, 1 2 3,&e., which establish communication between the exterior air and thecentral chamber. The extent of the openings of the ducts may be variedat pleasure, so as to control the admission of air to the centralchamber, by means of sliding valve-bars I I, one for each set of ductsshown,

' each bar having a series of ports, 0 c, corresponding in number andrelative position with the ducts. By sliding the bars in and out thesize of the openings of the ducts may be varied.

Upon the base A is placed a stove, S, of any desired construction. Theproducts of combustion from the stove pass to the exit flue F through anenlarged casing, L. XVithin this casing is a hot-air drum, H, from theupper end of which there extends through the wall of the casing anexit-flue, M, which conveys the heated air to any desired locality. Thelower portion of the drum H communicates by a flue, O, with the centralchamber, D, of the hollow base. The cold air from the floor passesthrough the hollow base to the heating-drum, where it is heated andconveyed away, the described construction insuring a strong draft of airthrough the base and drum, thus causing a rapid circulation of air inthe apartment in which the stove is placed and insuring a more equabletemperature throughout the apartment. 7

The drum H is held within the casing L at the bottom by a ring, 7;, andsupports a a, attached to the ring and resting on the innerwall of thecasing and attached thereto. The supporting-ring k is unconnected to thedrum,

the lower conical end of the drum extending therein sufficiently to holdit in place. Braces b I) at the top, interposed between the casing anddrum, hold the latter in proper central position.

To facilitate the heating of the air in the drum,and to check the toorapid escape of the products of co nibustion from the stove through thecasing, the drum is contracted at its center,as shown, and encirclingits contracted portion is a horizontal annular shelf, E, fixed to thecasing. This shelf deflects the upward currents of the products ofcombustion against the drum, thus facilitating the heating thereof.

In Figs. 3 and at is shown a modification of the invention applicable toa lieatingstove designed to heat .only the apartment in which the stoveis placed. In these figures a circular instead of a rectangular base isshown, and the air passing through the base is conveyed not toadrum,butto the bottom of the st.ove,the air rising therefrom along theexterior surface of the stove. In this case the central chamber is atthe center of the circular base, and the air-ducts lead radially fromthe entire periphery of the base to the central chamber. The sliding valve-bars are in this case replaced by a circular valve-ring, J,encircling the periphery of the base. In other respects the constructionand function of the ring J are similar to the valve-bars I I.

The central chamber is open at the top, and above it is arranged averticallymovable drum, B, the upper open mouth of'which is immediatelybeneath the bottom of the stove.

The position of the drum B may be adjusted by setscrews O O,which bearagainst a circu- IOO lar rim or flange, R, on the base. This arm is theequivalent of the conducting-flue O in the first-described construction.

I claim as my invention 1. A hollow base for stoves and furnaces, thesame having a central chamber, ducts leading from the exterior of thebase to said central chamber, and an outlet-passage leading upwardlyfrom said central chamber, substantially as set forth.

2. Ahollow base for stoves and furnaces, the same having a centralchamber,and ducts leading from its exterior to said chamber incombination with valves for controlling the size of the openings of saidd ucts, substantially as set forth.

3. A hollow base for stoves and furnaces, the same having a centralc.hamber,and ducts leading from its exterior to said chamber, in

combination with a casing through which the products of combustion fromthe stove or furnace pass, a hot-air drum within said casing, and a flueleading from said chamber in said hollow base to the lower part of saiddrum, substantially as set forth.

4. The outer casing, the ring k therein, and the supports a a, holdingsaid ring centrally in said casing, in combination with the hot air drumWithin said casing, having a conical lower end set into said ring, andbraces 12 b, interposed between the upper end of the drum and thecasing, substantially as set forth.
